ABSTRACT

The present invention relates to bicyclic heterocycles, and pharmaceutical compositions of the same, that are inhibitors of the FGFR3 enzyme and are useful in the treatment of FGFR3-associated diseases such as cancer.

FIELD OF THE INVENTION

The present disclosure relates to bicyclic heterocycles, andpharmaceutical compositions of the same, that are inhibitors of theenzyme FGFR3 and are useful in the treatment of FGFR3-associateddiseases such as cancer.

BACKGROUND OF INVENTION

The Fibroblast Growth Factor Receptors (FGFR) are receptor tyrosinekinases that bind to fibroblast growth factor (FGF) ligands. There arefour FGFR proteins (FGFR1-4) that are capable of binding ligands and areinvolved in the regulation of many physiological processes includingtissue development, angiogenesis, wound healing, and metabolicregulation. Upon ligand binding, the receptors undergo dimerization andphosphorylation leading to stimulation of the protein kinase activityand recruitment of many intracellular docking proteins. Theseinteractions facilitate the activation of an array of intracellularsignaling pathways including Ras-MAPK, AKT-PI3K, and phospholipase Cthat are important for cellular growth, proliferation and survival(Reviewed in Eswarakumar et al. Cytokine & Growth Factor Reviews, 2005).

Aberrant activation of this pathway either through overexpression of FGFligands or FGFR or activating mutations in the FGFRs can lead to tumordevelopment, progression, and resistance to conventional cancertherapies. In human cancer, genetic alterations including geneamplification, chromosomal translocations and somatic mutations thatlead to ligand-independent receptor activation have been described.Large scale DNA sequencing of thousands of tumor samples has revealedthat components of the FGFR pathway are among the most frequentlymutated in human cancer. Many of these activating mutations areidentical to germline mutations that lead to skeletal dysplasiasyndromes. Mechanisms that lead to aberrant ligand-dependent signalingin human disease include overexpression of FGFs and changes in FGFRsplicing that lead to receptors with more promiscuous ligand bindingabilities (Reviewed in Knights and Cook Pharmacology & Therapeutics,2010; Turner and Grose, Nature Reviews Cancer, 2010). Therefore,development of inhibitors targeting FGFR may be useful in the clinicaltreatment of diseases that have elevated FGF or FGFR activity.

The cancer types in which FGF/FGFRs are implicated include, but are notlimited to: carcinomas (e.g., bladder, breast, cervical, colorectal,endometrial, gastric, head and neck, kidney, liver, lung, ovarian,prostate); hematopoietic malignancies (e.g., multiple myeloma, chroniclymphocytic lymphoma, adult T cell leukemia, acute myelogenous leukemia,non-Hodgkin lymphoma, myeloproliferative neoplasms, and Waldenstrom'sMacroglubulinemia); and other neoplasms (e.g., glioblastoma, melanoma,and rhabdosarcoma). In addition to a role in oncogenic neoplasms, FGFRactivation has also been implicated in skeletal and chondrocytedisorders including, but not limited to, achrondroplasia andcraniosynostosis syndromes.

There is a continuing need for the development of new drugs for thetreatment of cancer, and the FGFR3 inhibitors described herein helpaddress this need.

Compounds of formula 1-4 can be prepared via the synthetic routeoutlined in Scheme 1. A halogenation reaction of 1-1 can be carried outusing an appropriate reagent, such as N-iodosuccinimide, followed by NHprotection to afford compounds of formula 1-2. The compounds of formula1-2 can be cross-coupled with Cy¹-M, in which M is a boronic acid,boronic ester or an appropriately substituted metal [e.g., M is B(OR)₂,Sn(Alkyl)₃, or Zn—Hal], under standard Suzuki Cross-Coupling conditions(e.g., in the presence of a palladium catalyst and a suitable base), orstandard Stille cross-coupling conditions (e.g., in the presence of apalladium catalyst) (ACS Catalysis 2015, 5, 3040-3053), or standardNegishi cross-coupling conditions (e.g., in the presence of a palladiumcatalyst) (ACS Catalysis 2016, 6, 1540-1552) to generate compounds offormula 1-3. Buchwald-Hartwig reaction of 1-3 with an appropriate aminecan then be carried out using standard Buchwald-Hartwig cross-couplingconditions (e.g., in the presence of a palladium catalyst and a suitablebase) (Chem. Sci. 2011, 2, 27-50), followed by deprotection of theprotective group to afford compounds of formula 1-4.

Compounds of formula 2-2 and 2-3 can be prepared via the synthetic routeoutlined in Scheme 2. A Buchwald-Hartwig reaction of 1-3 (prepared usingprocedures from Scheme 1) with an appropriate amine can be carried outusing standard Buchwald-Hartwig cross-coupling conditions (e.g., in thepresence of a palladium catalyst and a suitable base) to affordcompounds of formula 2-1. Alkylation of 2-1 can be conducted usingappropriate base (e.g. LDA) and R²⁰-Hal (Hal is a halide, such as Cl,Br, or I) to afford mono and double alkylated products 2-2 and 2-3.

Compounds of formula 1-4 can be alternatively prepared via the syntheticroute outlined in Scheme 3. Protection of 1-1 results in the formationof compounds of formula 3-1. Reaction of 3-1 with an appropriate amineunder standard Buchwald-Hartwig cross-coupling conditions (e.g., in thepresence of a palladium catalyst and a suitable base) followed bydeprotection can afford compounds of formula 3-2. A halogenationreaction of 3-2 can be carried out using an appropriate reagent, such asN-iodosuccinimide, followed by NH protection results in compounds offormula 3-3. The compounds 3-3 can then be cross-coupled with Cy¹-M,where M is a boronic acid, boronic ester or an appropriately substitutedmetal [e.g., M is B(OR)₂, Sn(Alkyl)₃, or Zn-Hal], under standard Suzukicross-coupling conditions (e.g., in the presence of a palladium catalystand a suitable base) (Tetrahedron 2002, 58, 9633-9695), or standardStille cross-coupling conditions (e.g., in the presence of a palladiumcatalyst), or standard Negishi cross-coupling conditions (e.g., in thepresence of a palladium catalyst) to generate intermediate 3-4, whichcan then be deprotected to afford compounds of formula 1-4.

Compounds of formula 4-8 can be prepared via the synthetic routeoutlined in Scheme 4. A halogenation reaction of 4-1 can be carried outusing an appropriate reagent, such as N-bromosuccinimide, followed byprotection with acetic anhydride to afford compounds of formula 4-2. Areaction of 4-2 with isopentyl nitrite results in the formation of 4-3,which can then be deprotected to afford 4-4. Halogenation and protectionof 4-4 using N-iodosuccinimide and an appropriate protective group candeliver compound 4-5. A cross-coupling reaction can be performed between4-5 and Cy¹-M in which M is a boronic acid, boronic ester or anappropriately substituted metal [e.g., M is B(OR)₂, Sn(Alkyl)₃, orZn-Hal], under standard Suzuki cross-coupling conditions (e.g., in thepresence of a palladium catalyst and a suitable base), or standardStille cross-coupling conditions (e.g., in the presence of a palladiumcatalyst), or standard Negishi cross-coupling conditions (e.g., in thepresence of a palladium catalyst) to generate compounds of formula 4-6,which can be used in Buchwald-Hartwig cross-coupling reaction to providecompounds of formula 4-7. Finally, another cross-coupling reactionbetween 4-7 and an appropriate coupling partner can be performed usingsimilar conditions as described for the transformation from 4-5 to 4-6or transformation from 4-6 to 4-7 to afford compounds of formula 4-8.

Labeled Compounds and Assay Methods

Another aspect of the present invention relates to fluorescent dye, spinlabel, heavy metal or radio-labeled compounds of the invention thatwould be useful not only in imaging techniques but also in assays, bothin vitro and in vivo, for localizing and quantitating the FGFR enzyme intissue samples, including human, and for identifying FGFR enzyme ligandsby inhibition binding of a labeled compound. Substitution of one or moreof the atoms of the compounds of the present disclosure can also beuseful in generating differentiated ADME (Adsorption, Distribution,Metabolism and Excretion). Accordingly, the present invention includesFGFR binding assays that contain such labeled or substituted compounds.

The present invention further includes isotopically-labeled compounds ofthe invention. An “isotopically” or “radio-labeled” compound is acompound of the invention where one or more atoms are replaced orsubstituted by an atom having an atomic mass or mass number differentfrom the atomic mass or mass number typically found in nature (i.e.,naturally occurring). Suitable radionuclides that may be incorporated incompounds of the present invention include but are not limited to ²H(also written as D for deuterium), ³H (also written as T for tritium),¹¹C, ¹³C, ¹⁴C, ¹³N, ¹⁵N, ¹⁵O, ¹⁷O, ¹⁸O, ¹⁸F, ³⁵S, ³⁶Cl, ⁸²Br, ⁷⁵Br,⁷⁶Br, ⁷⁷Br, ¹²³I, ¹²⁴I, ¹²⁵I and ¹³¹I. The radionuclide that isincorporated in the instant radio-labeled compounds will depend on thespecific application of that radio-labeled compound. For example, for invitro FGFR enzyme labeling and competition assays, compounds thatincorporate ³H, ¹⁴C, ⁸²Br, ¹²⁵I, or ³⁵S will generally be most useful.For radio-imaging applications ¹¹C, ¹⁸F, ¹²⁵I, ¹²³I, ¹²⁴I, ¹³¹I, ⁷⁵Br,⁷⁶Br or ⁷⁷Br will generally be most useful. One or more hydrogen atomsin a compound of the present disclosure can be replaced by deuteriumatoms (e.g., one or more hydrogen atoms of a C₁₋₆ alkyl group of Formula(I) can be optionally substituted with deuterium atoms, such as —CD₃being substituted for —CH₃). In some embodiments, alkyl groups inFormula (I) can be perdeuterated.

One or more constituent atoms of the compounds presented herein can bereplaced or substituted with isotopes of the atoms in natural ornon-natural abundance. In some embodiments, the compound includes atleast one deuterium atom. In some embodiments, the compound includes twoor more deuterium atoms. In some embodiments, the compound includes 1-2,1-3, 1-4, 1-5, or 1-6 deuterium atoms. In some embodiments, all of thehydrogen atoms in a compound can be replaced or substituted by deuteriumatoms.

Synthetic methods for including isotopes into organic compounds areknown in the art (Deuterium Labeling in Organic Chemistry by Alan F.Thomas (New York, N.Y., Appleton-Century-Crofts, 1971; The Renaissanceof H/D Exchange by Jens Atzrodt, Volker Derdau, Thorsten Fey and JochenZimmermann, Angew. Chem. Int. Ed. 2007, 7744-7765; The Organic Chemistryof Isotopic Labelling by James R. Hanson, Royal Society of Chemistry,2011). Isotopically labeled compounds can be used in various studiessuch as NMR spectroscopy, metabolism experiments, and/or assays.

Substitution with heavier isotopes, such as deuterium, may affordcertain therapeutic advantages resulting from greater metabolicstability, for example, increased in vivo half-life or reduced dosagerequirements, and hence may be preferred in some circumstances. (seee.g., A. Kerekes et. al. J. Med. Chem. 2011, 54, 201-210; R. Xu et. al.J. Label Compd. Radiopharm. 2015, 58, 308-312). In particular,substitution at one or more metabolism sites may afford one or more ofthe therapeutic advantages.

The radionuclide that is incorporated in the instant radio-labeledcompounds will depend on the specific application of that radio-labeledcompound. For example, for in vitro adenosine receptor labeling andcompetition assays, compounds that incorporate ³H, ¹⁴C, ⁸²Br, ¹²⁵I, ¹³¹Ior ³⁵S can be useful. For radio-imaging applications ¹¹C, ¹⁸F, ¹²⁵I,¹²³I, ¹²⁴I, ¹³¹I, ⁷⁵Br, ⁷⁶Br or ⁷⁷Br can be useful.

It is understood that a “radio-labeled” or “labeled compound” is acompound that has incorporated at least one radionuclide. In someembodiments the radionuclide is selected from the group consisting of³H, ¹⁴C, ¹²⁵I, ³⁵S and ⁸²Br.

Synthetic methods for incorporating radio-isotopes into organiccompounds are applicable to compounds of the invention and are wellknown in the art.

The present disclosure can further include synthetic methods forincorporating radio-isotopes into compounds of the disclosure. Syntheticmethods for incorporating radio-isotopes into organic compounds are wellknown in the art, and an ordinary skill in the art will readilyrecognize the methods applicable for the compounds of disclosure.

A radio-labeled compound of the invention can be used in a screeningassay to identify/evaluate compounds. In general terms, a newlysynthesized or identified compound (i.e., test compound) can beevaluated for its ability to reduce binding of the radio-labeledcompound of the invention to the FGFR4 enzyme. Accordingly, the abilityof a test compound to compete with the radio-labeled compound forbinding to the FGFR4 enzyme directly correlates to its binding affinity.

A labeled compound of the invention can be used in a screening assay toidentify and/or evaluate compounds. For example, a newly synthesized oridentified compound (i.e., test compound) which is labeled can beevaluated for its ability to bind an FGFR protein (e.g., FGFR3) bymonitoring its concentration variation when contacting with the FGFR,through tracking of the labeling. For example, a test compound (labeled)can be evaluated for its ability to reduce binding of another compoundwhich is known to bind to a FGFR protein (i.e., standard compound).Accordingly, the ability of a test compound to compete with the standardcompound for binding to the FGFR protein directly correlates to itsbinding affinity. Conversely, in some other screening assays, thestandard compound is labeled and test compounds are unlabeled.Accordingly, the concentration of the labeled standard compound ismonitored in order to evaluate the competition between the standardcompound and the test compound, and the relative binding affinity of thetest compound is thus ascertained.

Kits

The present invention also includes pharmaceutical kits useful, forexample, in the treatment or prevention of FGFR-associated diseases ordisorders (e.g., cancer), obesity, diabetes and other diseases referredto herein which include one or more containers containing apharmaceutical composition comprising a therapeutically effective amountof a compound of the invention.

Instructions,either as inserts or as labels, indicating quantities of the componentsto be administered, guidelines for administration, and/or guidelines formixing the components, can also be included in the kit.

The invention will be described in greater detail by way of specificexamples. The following examples are offered for illustrative purposes,and are not intended to limit the invention in any manner. Those ofskill in the art will readily recognize a variety of non-criticalparameters which can be changed or modified to yield essentially thesame results.

Example A

FGFR Enzymatic Assay

The inhibitor potency of the exemplified compounds was measured in anenzyme assay that measures peptide phosphorylation using FRETmeasurements to detect product formation. Inhibitors were seriallydiluted in DMSO and a volume of 0.5 μL was transferred to the wells of a384-well plate. For FGFR3, a 10 μL volume of FGFR3 enzyme (Millipore)diluted in assay buffer (50 mM HEPES, 10 mM MgCl₂, 1 mM EGTA, 0.01%Tween-20, 5 mM DTT, pH 7.5) was added to the plate and pre-incubated fora time between 5-10 minutes and up to 4 hours. Appropriate controls(enzyme blank and enzyme with no inhibitor) were included on the plate.The assay was initiated by the addition of a 10 μL solution containingbiotinylated EQEDEPEGDYFEWLE peptide substrate (SEQ ID NO: 1) and ATP(final concentrations of 500 nM and 140 μM respectively) in assay bufferto the wells. The plate was incubated at 25° C. for 1 hr. The reactionswere ended with the addition of 10 μL/well of quench solution (50 mMTris, 150 mM NaCl, 0.5 mg/mL BSA, pH 7.8; 30 mM EDTA with Perkin ElmerLance Reagents at 3.75 nM Eu-antibody PY20 and 180 nM APC-Streptavidin).The plate was allowed to equilibrate for ˜1 hr before scanning the wellson a PheraStar plate reader (BMG Labtech).

GraphPad prism3 was used to analyze the data. The IC₅₀ values werederived by fitting the data to the equation for a sigmoidaldose-response with a variable slope.Y=Bottom+(Top−Bottom)/(1+10{circumflex over ( )}((LogIC₅₀−X)*HillSlope))where X is the logarithm of concentration and Y is the response.Compounds having an IC₅₀ of 1 μM or less are considered active.

Table 1 provides IC₅₀ data for compounds of the invention assayed in theFGFR Enzymatic Assay after dilution in assay buffer, added to the plateand pre-incubated for 4 hours. The symbol: “+” indicates an IC₅₀ lessthan 10 nM; “++” indicates an IC₅₀ greater than or equal to 10 nM butless than 30 nM; “+++” indicates an IC₅₀ greater than or equal to 30 nMbut less than 200 nM; and “++++” indicates an IC₅₀ greater than or equalto 200 nM.
